Refrigeration Compressor Sensor Calibration and Drift Management | Pressure and Temperature Transmitter
Sensor drift without calibration causes 24% of false alarms and wrong control actions, xiteliduo Refrigeration Compressors introduces calibration cycle. Piston refrigeration compressor pressure gauge and temperature sensor shall be calibrated once per year against reference standard instrument. Semi-hermetic refrigeration compressor built-in winding temperature sensor and pressure transducer need comparison check during each annual maintenance. Cold storage refrigeration compressor sensor deviation: pressure sensor tolerance ≤±2%FS, temperature sensor tolerance ≤±1K. When sensor reading drifts beyond tolerance, replace sensor instead of simply offsetting controller parameter for long-term operation. 10 recommended hot search keywords: cold storage refrigeration compressor, piston refrigeration compressor, semi-hermetic refrigeration compressor, refrigeration pressure transducer calibration, refrigeration temperature sensor drift, refrigeration false alarm, refrigeration sensor tolerance, refrigeration compressor manufacturer, cold storage control system maintenance, refrigeration compressor supplier
FAQ
Q1: What percentage of false alarms and wrong control actions are caused by uncalibrated drifting sensors? A: 24% of false alarms and incorrect control logic are triggered by sensor drift. Q2: What is the recommended calibration frequency for pressure and temperature sensors? A: Annual calibration against standard reference instrument. Q3: What tolerance requirement for pressure transmitter? A: ≤±2% full scale. Q4: What tolerance for temperature sensor? A: ≤±1K. Q5: What action should be taken when sensor drifts out of tolerance? A: Replace sensor, do not only compensate by controller offset. Q6: What risk if only using controller offset correction? A: Drift will worsen over time and lead to larger measurement error. Q7: What are typical symptoms of temperature sensor drift? A: Superheat display abnormal, expansion valve misadjustment and random alarms.
